    /**
    @brief
        This class implements a method of displaying a Notification with information to an input command and the key the command is mapped to.
        The message that is displayed is a string made out of the concatenation of the preMessage, the key the specified command is mapped to and the postMessage.

        In use it would like this:
        @code
        <CommandNotification preMessage="Please press " command="someCommand" postMessage=" to do something." sender="me">
            <events>
                <trigger>
                    <PlayerTrigger />
                </trigger>
            </events>
        </CommandNotification>
        @endcode
        Upon being triggered this would display the @ref orxonox::Notification "Notification" "Please press {the binding of the specified command} to do something".
        For more information on what can be used for @code <PlayerTrigger /> @endcode see the @ref orxonox::NotificationDispatcher "NotificationDispatcher" documentation.
